DRV8825 VS A4988: Key differences between the DRV8825 and A4988

The following are the key differences between DRV8825 and A4988 

The DRV8825 has a 1/32 microstepping capability, whereas the A4988 only has a 1/16 microstepping capability. Higher microstepping  provides smoother, quieter operation, but it isn't always necessary.

The current limit potentiometer is located somewhere else.

The reference voltage and the current limit have distinct relationships.

The DRV8825 requires a minimum STEP  pulse duration of 1.9 seconds, while the A4988  requires a minimum pulse duration of 1 second.

A higher voltage motor power source can be used with the DRV8825 (45 V vs 35 V). This means it's less likely to be harmed by LC voltage spikes.

Without any additional cooling, the DRV8825 can deliver a slightly greater current than the A4988.

 


How to control a stepper motor with DRV8825 driver?

The stepper motor may be controlled using only a few pins on the DRV8825. The A4988 stepper motor driver carrier's pinout and interface are essentially identical to those of the module. The following is the DRV8825 diagram.

DRV8825 schematic.jpg

DRV8825 Diagram

To drive the stepper motor, the microcontroller is connected to the module's DIR, STEP, and FAULT pins. The number of steps is controlled by the STEP pin, while the direction is controlled by the DIR pin.

The DRV8825's FAULT pin is shorted to the SLEEP pin, so driving the Fault pin low disables the entire chip. Microstep pins (M0, M1, and M2) are used to regulate the driver module's step functionality. In the above circuit, the M0, M1,and M2 pins are left unconnected, indicating that the driver will operate in full-step mode. The DRV8825 is vulnerable to voltage spikes since it has low-ESR ceramic capacitors onboard. As a result, a 47f capacitor should be installed across the motor power supply pins at the very least. It's commonly used to power NEMA series stepper motors including the NEMA17, NEMA23, and NEMA34.
